Specification of Letters Patent.

pplication filed ovember 1, 1920i Serial No. 421,033.

To all whomy t may concern.'

Be it known that I,`WILLIAM T. Woon, a citizen of the United States of America, residing at3860 Park` avenue, St. Louis, State of Missouri, have invented certain new and `useful Improvements in Conveyers, of which the following is a specification.

The object of my invention is toproduce a conveyer that is particularly adapted for use in packing houses in which hogs or other animals are dressed. A more particular object is to produce a conveyer inlwhich the hooks holding the hogs etc. will be automatically fed orfdelivered to the operator and move along at` such a speed that the various operators can perform their* respective operations consecutively and so that the hog etc. `will be delivered automatically after being dressed,` quartered etc. and `one in which the operation will be continuous i. e., tosay in which the hooks that support the hogs will be delivered to the point of be-` i i ginning after the dressed hogsor parts of hogs have been removed. `The conveyer 1s built as an endless conveyer.

With the above purposes in view, my invention consists in certain novel features of `construction and arrangements of partsyas will be hereinaftermore "fully described, pointed out in the claims and illustratedin the accompanying drawings in which#- Figure 1 is a front elevationofa portion of an endless track with my device attached. Fig." 2isa plan view "of a portion of` an `endless track showing my device? with the driving chain omitted.

Fig. 3 is a perspective view ofthe cham tripping elementof my device and Fig. 4 is a perspective `of the feeding device of my invention. i

Numeral 5 indicates a track supported by hangers 6 by means of bolts 7. The hangers 6 are supported by the roof or ceiling by means of the bolts `8.

`be automatically fed,to the having the projections 15 secured thereto at regular intervals as shown in Fig. `1. This sprocket chain is endless and traverses sprocket wheels at both ends (not shown.) This `sprocket chain is the driving element and moves from right to left in Fig. 1. When the projection 15 engages the strap l1, andmoves as indicated, it pushes the roller 9. the strap 11 and the hooks13 to the left. The hogs or Vother animals to be dressediare secured to the hooks 13 and are delivered to the track of Fig. 1 from the right. Without my automatic feeding de- ,vice` the roller 9 would roll down the incline of track 5 to the left until it came to the operativerange of the sprocket chain 14, and i would not be delivered in the proper consecutive` time interval. The operators on the hogs stand between the two left hangers 6, and under the hook delivering mechanism,

each operator performing one operation while the hog etc. is movinf toward the left.

The hog must be positively and constantly moved' toward the VHleftwithout the assistance of the operator and at such a speed to permiteach operator to 4perform his task before the hog is moved tothe position of thefollowing operator, andthe hogs must operators from the right; `My device for accomplishing this result is the following.

Numeral 16 indicates a bracket which is secured to the side of the track 5 by means of the bolts 17, which bracket supports the hook feeding device which consists of a frame 18 which is firmly secured to the bracket 16 as best shown in Fig. 4. This frame consists ofthe horizontal arm 19, and

the vertical guide20, which guide has its which is best shown in Fig. 4. The horizontal portion 24 is so positioned that in its horizontal position, it rests in the fork of the vertical guide 20. A coiled spring 26 is Isecured to the horizontal arm 19 an the Yso horizontal portion 24, of the movable arm 21k-so as to normally hold them in the position shovvn in Fig. Ll. To the movable arm v 2l is secured the eye 27 as shovvn in Fig. l.

lty Will be seen that When the eye 27 is pulled to the left the arm 25 Will be raised.

Numeral 28 indicates a second bracket, best'shoWn in Fig. 3 Which is secured to the side of the track by means of the bolts 29. The .bracket 28, has Jformed integral there- With a vertical element 3() on which is positioned the plate 3l. Numeral 32 indicates a tripping linger Which is rotatively secured on theplate 3l by means of the bolt 33 as best shown in Fig. 3. Numeral 34 indicates an eye which is secured to the external end oi the tripping finger 32. Numeral 35 indicates a rod having eyes at both ends, one of which is rotatively secured to the eye 27 and the other tothe eyelid. The end oi' the tripping linger 32 is positioned in the line of travel of the projections and the arm 25 in'its normal position is in the line of travel of the upper end of the straps 11. Numeral 86 indicates a stopper secured in the plate 3l, rto serve as a movement limiting means for the tripping finger 32. The operation of my device is as follows:

k.The projection l5 in its travel to the lett engages the-end of the tripping linger 32 and rotates it von the boltY 33 to the left, thereby permitting the projection l5 to move unobstructed `to the left. The rotation of. the tripping linger pulls ,the rod to the left, thereby rotating the movable arm 2lon' its bolt in `an anti-clockwise direction, thereby extending the spring 26 and raising the arm A25, thereby removing the obstruction in the path of the Anext roller and hook that is to be edinto the operative range of the track 5. The roller and hook thereupon roll down the track to the proper position, and the arm 25 .is again pulledto'its normal position by the spring 2G, thereby preventing the following roller and hook from rolling down the track 5. lt will he seen that the distance between the projections 15 and the speed of the sprocket chain li will determine the intervals at which the rollers will be led to an operative position.

lhat l claim and mean to scrure by lietters Patent isl. ln Combination with a track, rollers mounted on said track in rolling engagement, straps secured to said rollers in rotative engagement, hooks secured to said straps, an endless driving` chain having projections thereon, a load delivering device consisting of a movable obstruction in the path of said rollers on said track and means for selectively moving said obstruction iu and out of the path of said rollers, a tripping ringer, operatively connerted to said load delivery device, and means secured to said chain for contacting said tripping linge at regular intervals.

2. ln combination with a track, rollers mounted on said track in rolling` engagement, said track being inclined in one portion thereof, straps secured to said rollers in rotative engagement, hooks secured to said straps, an endless driving` chain havingprojections thereon, a load delivering device consisting of a movable obstruction in the path of said rollers on said track, and means 'tor selectively moving said obstruction in and out of the path oiE said rollers, a tripping linger operatively connected to said delivering device and means secured to said chain for contacting said tripping finger at regular intervals said tripping finger being normally positioned in the path of said track rollers.

In testimony whereof I afiix my signature.
